The data looks like it agrees with your coverup hypothesis. The CDC is comparing 2021 with 2020, instead of with the pre-pandemic 2019.
There is a chance of defeating the coverup if people make a case that comparing 2021 with 2020 is invalid because covid was a confounder in 2020 and that, instead, 2021 should be compared with 2019.

Wouldn't covid also be a confounder in 2021?
Covid would be a confounder to vax as cause of death in 2021, but the point is that 2019 is a better baseline than 2020.
